1T0 all whom it may. concern:

Be it known that 1, JOHN WILLARD MOGUIRE,

a citizen of the United States, and a resident State of North Dakota, have made certain new and useful improvements in Motor-Flows, of which the following is a specification.

My invention is an improvement in gangplows-propelled by steam, tractioncngines, or other motors. The plows proper are arranged in gang in a frame of peculiar construction, which is connected with the motor proper, the plows being in a line inclined or oblique to the axle of the motor, so that one works slightly in advance of or in rear of the adjacent one. Eachplow is adapted for independent adjustment vertically not only as a whole or bodily, but also at the point and heel, so that its pitch may be varied as reuired for entering the soil or running at diferent depths therein.

The invention includes means for efl'ecting such vertical adjustment and change of pitch, also the construction of the frame and means for'supportin and guiding the same and connccting'it with the motor, all as will be here inafter described, and as illustrated in the ac companying drawings, in which Figure 1 is'a side elevatlon of a portion of the. plow-frame, partbeing in vertical section, one pf the plows of the gang being shown elevated or inthe position required when the plow is out of use or traveling from one point to another. Fig. 2 is a view'similar in essential-s toFig. 1, save that the plow proper is shown in position for work in the soil. Fig. 3

is a plan view of a portion of the frame and a one of the plows of a gang arranged therein.

4 includes face and side vlews' of the coupling by which the plow-frame is connected with the axle of the motor. Fig. 5 shows side and. edge views of portions of such coupling. Fig. 6 is a rear end view of a portion of the frame, together with one of the plows proper connected therewith. Fig. 7 is a vertical transverse section in a plane adjacent to one of the transporting-wheels, upon which the plow frame is supported. Fig. 8 is a plan View. of the plowira1ne, together with the couplings that connect it with the motor and the means for steering the frame with its attached plows Referring in the first instance to Figs. 3

and 8, it will be seen that I- provide a frame which is constructed of bar and channel iron and connected by bars 1 2 withthe axle 3 of the motor. Three bars 4 5 6. extend parallel to each other and diagonally or inclined to the axle of the'motor, the same being spaced apart, and the bars 4 5, which are nearer each other, being rigidly connected with the draft bars 1 and 2. The rear bar 6 is connected with the parallel bar 5 by means of a series of bars 7, having their ends bent laterally at an obtuse angle and secured by bolts. The bars 4 5 are similarly connected by short bars 7. The bar 4 is in turn connected with a cr0ss-bar 18 by means of parallel bars 7 I thus form a light but strong and rigid frame. The

. plows proper are arranged in the spaces .be-

tween the transverse bars 7 and the main bars 5 and 6, as will be presently described in detail. The front ends of the draft-bars 1 2 are connected with an extended hub 8 (see Fig. 4) of the motor-axle 3 by means of a coupling 9. (See Fig. 5.) The latter is secured upon the journal of the hub 8 by means of a screw 10, (see Fig. 4,) and the draft-bars 1 2 are in turn suitably bolted to a pendent shank of the part 9, as will be readily understood. It is apparent that by this construction and arran ement of parts the front end of the plowrameis duly supported. The rear or main portion of the plow-frame is supported upon transporting-wheels 11, whose arrangement is indicated 1n F g. 8. As shown in Figs.

1 and 7, these wheels 1] are mounted upon an motor and gan plow as a whole. -To this end I attach t6 t e bifurcated frames 12 horizontal arms 15, and I connect the two arms by a rod 16, the same having a lever-arm 17, that extends forward into proximity to a cross bar 18, that rigidly connects the draft-bars 1. The lever 17 1s connected by chains 19 with rods 20, connected with the front pivoted axle 1 tor-carriage is turned on its pivot the lever I? will be swung correspondingly to the right or left and that thereby the running-wheels 11 will besimilarlv adjusted at an inclination right or left, so that the plow-frame will be guidedin the arc of acirclc corresponding to that described by the front wheels of the mo: tor, with which the said wheels 11 track, as shown.

. The arrangement of plows proper and their operating mechanism with and relative to the irame will now be described. As shown in Figs. 1 and '2, the plow proper is construct ed in a well-known manner and provided with a curved channeled beam 23, and to this a rolling colter 24 and a gage-wheel are attached in the usual way. To the plowclevis 26 is attached a dratt-bar 26, which'is pivoted to :1 lug pendcntirom the frame. Theclevis is further connected by a rod 27 and swivel-clevis 28 with the shorter arm 29 of a lever 30, which is pivoted at 31 in suitable bearings, the same being; formed in part of a toothed'segnlent 32, which is rigidly secured in place on the frame of the machine. The longer arm 30 of said lever is provided with a slidable pawl 33 for engaging the toothed segment, the same being operated by a hand-lever and rod 34. in the usual way. parent that by swinging the lever 30 in a vertical )lane forward or back the front end of the pi lower correspondingly.

The rear end of the plow-beam 23 is connected by a clevis 35 and rod 36 with an elbow-lever 37, which pivoted at its angle 38 to a vertical stander 39, having diagonal braces 39, secured rigidly to the frame of the machine. The rear arm of the elbow-lever 3? projectsupward and rearward and is suitably. constructed to adapt it to be grasped and manipulated for adjusting the plow as may be required. The shorter arm of said lever is connected by a rod e0 with a device il, which .in view of its form and function I term a qua drant-l ever.

Asshown best in Figs. 2 and 3, the part 41 consists of a curved head or segment composed of two parallel bats which are connected at their ends and between which the lever SOworks, and a rigid bai' 4.1,which is connected with said curved bars and pivoted at 31, or, in other words, at the same point Where the lever 30 is fulcrurned. The clevis 35 before referred .to straddles the plowbeam 23 and is pivoted. thereto at a point adjacent to the plow-shearer inoldboard. The upper end of said clevis 35 is pi'votally eonnected with the middle portion of the U it is ap-' ow-beain 23 will be adjusted higher or eration of the parts connected with the plow i proper and thus far described will now be understood. When the lever 30 is adjusted in vertical position, as shown in Fig. 1, both the front and rear ends of the plowheain will be raised, and thereby the'plow proper will beheld elevated above the round as required when not in use or when t is ma chine traveling or being transported from place to place. The plow is, however, capable of adjustment for inclining the point downward as required to give it the proper pitch. for entering the soil, or its point may be raised and its heel inclined downward, as shown by dotted lines, Fig. 2, these movemcnts being effected by one and the same lev ver 30 through the medium of its connections 'with the plow, as before describedthat is to 'sav.' when the lever 30 is thrown back or mclined to the left, as shown in Fig. 2 ,the l'ront or clevis end of the plow-beam will obviously be carried downward and the plow lowered a whole so that the plow will be, held in the position required for actual work. it will be seen that when the lever 30 is thrown to -the position iiulicated. it carries the quadrant-lever 41 with it; so that, through the medium of the rod 4(), the elbow-lever 37 is tilted. in such manner as to allow the rear end of the plow-beani to be lmvered. If, on the other hand, the lever 30 be thrown to the right, as shown by dotted lines, Fig. 2, the front end of the plow-beam will be raised through the medium of the elevis-rod 27 and the rearend of the plow-beam will be similarly raised through the medium of the elbow-lever 37, connecting-rod 36, and clevis Thus, in brief, the

front end of the plow-beam will be raised without stirring, the rear end, so as to run the plow up out of the ground, or, reversely, the

front end may be pitched downwardwithout changing the position of the rear end. and, again, through the medium of the same level the plow proper may be raised bodily above the ground or soil.

Coil-springs 44 are connected at one end with the free end of the arch 42 by means of a rod or rods 45, and their opposite ends are attached to screws 46, which are adjustably connected with the opposite ends of avertical equalizing-bar 8, that is pivoted at its middle to a portion of the frame. The screws 46 and nuts 47 applied thereto, as shown in Figs. 1 and 2, provide for adjustmentoi' the tension of the springs as conditions may require. It is obvious thatthe bar 48 will rock, on its pivot so that the springs 44- may shift up and down, according as the plow proper is adeeaesr rusted higher or lower. These springs act for a double purpose-namely, one assists in raising the plow out of the ground and the other assists in steadying the plow in the ground, while both assist in holding the plow elevated when out of the ground.

It will be seen that by means of my invention as herein illustrated and described i provide a series of plows in gang, each of which works independently of the other, so that it may he raised or lowered without in any way all'ecting or interfering with the other; also, that by the lever mechanism. each plow may be easily manipulated for causing .it to enter the soil or taking the horizontal position therein or elevating its point to bring it quickly out of the soil; also, that I provide means to assist in raising and low erin g each plow as a whole and in holding; the rear end of each plow suspended while the front end is being lowered and that they assist in steadying the plow in the ground.

The plows will be ordinarily set to run at a uniform depth, but any of them may be adjusted to run at a greater or less depth than the others or thrown entirely out of action, according to the nature of the soil or obstructions or other conditions. lal ing; the frame and the *everal plows'together, they are adapted to work most effectively and may be attached to any traetioieeiigine.ot ordinaryconstruction.
